摘要： Example embodiments of systems and methods for data transmission between a contactless card and a client device in support of a FIDO authentication are provided. In an embodiment, upon receipt of a challenge issued by a server in connection with a pending transaction, the contactless card may authorize the client device to utilize a FIDO private key to respond to the challenge. If the response to the challenge is successful, the FIDO authentication may proceed and the transaction may be completed.

摘要： A dual-factor PIN based authentication system and method uses a cryptogram provided by a contactless card associated with the client in association with a PIN stored by the contactless card to authenticate the client. In some embodiments, cryptogram authentication may be preconditioned upon a PIN match determination by the contactless card. In other embodiments, the cryptogram may be formed at least in part using the personal identification number (PIN) stored on the contactless card encoded using a dynamic key stored by the contactless card and uniquely associated with the client. Authentication may be achieved by comparing the cryptogram formed using the PIN against an expected cryptogram generated an expected PIN and an expected dynamic key.

摘要： Various embodiments are generally directed to utilizing a steganographically encoded image with an offline and/or online verification or authentication protocol. A method for using the steganographic image can include: receiving or utilizing a steganographic image associated with a user at a third-party device, the steganographically encoded image including an identification of a user steganographically encoded with a fingerprint template of the user, and authenticating the user using the steganographically encoded image.

摘要： Example embodiments of systems and methods for data transmission system between transmitting and receiving devices are provided. In an embodiment, each of the transmitting and receiving devices can contain a master key. The transmitting device can generate a diversified key using the master key, protect a counter value and encrypt data prior to transmitting to the receiving device, which can generate the diversified key based on the master key and can decrypt the data and validate the protected counter value using the diversified key.

摘要： A contactless card can include a plurality of keys for a specific operation, e.g., encryption or signing a communication. The contactless card can also include an applet which uses a key selection module. The key selection module can select one of the plurality of keys and the applet can use the key to, e.g., encrypt or sign a communication using an encryption or signature algorithm. The contactless card can send the encrypted or signed communication to a host computer through a client device. The host computer can repeat the key selection technique of the contactless device to select the same key and thereby decrypt or verify the communication.
